In this paper we examine whether homeowning benefits children by testing whether children of homeowners stay in school longer than children of renters and whether daughters of homeowners are less likely to have children as teenagers than daughters of renters. We use both probit models and a bivariate probit technique which takes account of possible selection bias due to differences between pare...

This paper studies the effects of land use consolidation on consumption growth of farm households in Rwanda.

When nonworkers are included in the calculations, it is found that real wages of prime age black males increased less than 2 percent over the 1969-96 period in contrast to 9 percent wage growth observed among wor...

Background: Selection bias arises in clinical trials by reason of selective assignment of patients to treatment groups. Even in randomized clinical trials with allocation concealment this phenomenon can occur if future assignments can be predicted due to knowledge of former allocations. Objectives: Considering unmasked randomized clinical trials with allocation concealment the impact of selecti...
